配子体

Which are divided into sporophyte developed special-shaped generational and generational shaped gametophytes developed.

其中又分为孢子体发达的异形世代交替和配子体发达的异形世代交替。

The development of a gametophyte directly from a sporophyte without the occurrence of meiosis or spore formation.

无孢子形成，无孢子生殖，无孢子状态没有经过减数分裂或孢子形成而直接由孢子体进行的配子体发育

The results showed that the techniques could increase gametophyte adhesion rate by over 80%, made the seedlings stronger and the germination quality reach state standard of Class Ⅰ. The growth speed of clone adhesion (8~16 rows) was about 20 days faster than that of normal sporophyte seedling adhesion.

结果显示，这样的措施可使配子体附着率达到80%以上、幼苗健壮、出苗质量达到国家一类帘标准，使克隆采苗自8～16列c期间的生长发育速度较常规孢子体采苗后的生长发育速度快20 d。

In the Filicinophyta, Sphenophyta, and Lyophyta the embryo sporophyte produces a footlike structure that remains embedded in the tissues of the parent gametophyte plant, absorbing nutrients like the suspensor of higher plants.

在真蕨门 filicinophyta ，楔叶门 sphenophyta，和石松门 lycophyta 中，胚胎孢子体产生足状结构，仍然包裹于双亲配子体植物内。胚胎吸收营养的方式同高等植物从胚柄那样吸收营养一样。

Polysaccharides from wild tetraspotophytic and female gametic thalli of Gracilaria lemaneiformis (denoted as TP and FGP respectively) were extracted with hot water and a comparative study was made on their chemical characteristics and structures.

对青岛野生龙须菜四分孢子体和雌配子体中多糖的化学特性和结构进行了比较研究。

On the basis of results of our test,we suggest that low temperature pretreatment changes content of endogenous IAA and iPA of anther,thus interrupts previous developmental direction of pollen and induces microspores develop from a gametophytic way to a sporophytic way.

根据实验结果，推测低温预处理改变了花药内源IAA和iPA含量，阻断了花粉原来的发育方向，使其由配子体的发育途径转向孢子体的发育途径。

The arm repeat-containing 1 (ARC1) and the skp1-cul1-F-box proteins, belonging to the family of E3 Ub ligases, function in both the sporophytic and gametophytic self-incompatible responses, respectively.

自交不亲和反应也正是通过此途径实现的，ARC1(arm repeat containing 1)和SCFs (skp1-cul1-F-box-proteins)作为E3s分别在孢子体自交不亲和和配子体自交不亲和反应中起作用。

In order to trace the male cytoplasm transmission during double fertilization process, the mature gametophyte, zygote, proembryo and primary endosperm in Pelargonium hortorum Bailey and Rhododendron mucronulatum Turcz were investigated using transmission electron microscope and DNA staining technique.

本研究应用透射电镜及DNA荧光技术对天竺葵和杜鹃的成熟配子体以及在受精以后雄性细胞器的存在和分布进行了系统的细胞学研究，阐明了这两种植物中雌性生殖单位的超微结构特点及雄性和雌性细胞中质体和线粒体在受精作用中的传递。

Light microscope was employed to observe spore germination, protonemal development, gametophyte differentiation of Ptychomitrium sinense indoor cultured. The results showed that in P.

：通过室内人工培养中华缩叶藓的孢子，在光学显微镜下详细观察了其孢子萌发、原丝体发育及配子体发生的全过程。

In conclusion, high genetic identities were found in sporophytic offspring derived from mono-crossing of gametophyte clones of U. pinnatifida by means of both AFLP and microsatellite markers, however, subtle genetic variations were also detected.

总之，AFLP与微卫星的分析结果一致，即配子体克隆单一交配组合的孢子体后代呈现高度遗传相似性，但也存在细微的差异。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
